To all whom it may concern: I

Be it known that I, ALLEN K. BISHOP, a citizen of the United States, residing at Forsyth, in the county of Taney and State of Missouri, have invented certain new and useful Improvements in Combined Hay Rakes and Loaders, of which the following is a specification.

My invention relates to improvements in combined hay-rakes and loaders; and it consists' of the novel features of construction and combinations of parts hereinafter described and claimed.

The object of my invention is to provide a simple and practical machine of this character which will rake thehay, grass or the like from the field and then deliver it to a baling chamber wherein it is automatically compressed and baled.

The above and other objects of the invention, as will hereinafter appear, are attained in the preferred embodiment of my invention, illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the machine; Fig. 2 is a top plan view; Fig. 3 is a vertical longitudinal section; Figs. 4 and 5 are cross sectional views; and Figs. 6 and 7 are detail views.

Referring more particularly to the drawings, 1 denotes a suitable body or main frame mounted at its front end upon two supporting and driving wheels 2, and at its rear end on steering wheels 3. The latter are journaled on a pivoted axle 4 provided with a well lmown form of steering gear 5 arranged within convenient reach of the driver who occupies a seat 6 at the rear end of the body 1. a

The wheels 2 are loose upon ends of the lower section 7 of a two part front axle, the upper section or part 8 of which is secured by fastening devices consisting of opposing clamp plates 9 united by U-bolts 10 provided with upwardly and forwardly projecting portions to serve as pivots for a vertically tilting rake platform 11. The axle is made in two parts or sections to give it greater strength and to facilitate the mounting of the swinging frame carrying the platform. Therakeplatform is suitably secured to a frame formed preferably of two longitudinally-extending bent or L-shaped bars 12 having the upper or offset pivotal portionsof the bolts 10 arranged in the intermediate portions of their short upwardly projecting arms. united by a connecting bar or rod 13' and These short arms "are the long diverging front arms or ends of 1 the bars 12 are united by two parallel bars 6 p or rods 14, 15. These .rods 14, 15 have mounted upon them 'rake teeth 16 which form a rake equal in width to the machine, and the projecting extremities of the rod 15 have journaled upon them small ground wheels 17 to relieve the rake teeth of the weight of the platform and the parts thereon. The rake platform is tilted or adjusted vertically by means of block and tackle 18 arranged between the upper rear ends of the bars 12 and the side portions of the body or main frame 1, and having the cables 19 extending rearwardly under suitable guides and wound upon a Windlass 20 mounted beneath the rear portion of the body. The shaft of the Windlass 20 is connected by beveled gears 21 to an upwardly and rearwardly inclined operating shaft 22 carrying a hand wheel arranged within convenient reach of the driver.

Arranged upon the intermediate portion of the main frame or body 1 is a bale box or chamber 23 within which reciprocates a plunger 24. Said plunger is connected to one end of a pitman 25, the other end of which is connected to a wrist pin'26 between two crank disks 27 on the opposing inner ends of a two part shaft 28 journaled in suitable bearings on the front portion of the mainframe or body 1 adjacent the front axle. The crank shaft 28 has at its outer ends loosely mounted pinions 29 adapted to be locked to said shaft forrotation therewith by suitable clutches 30 and adapted to port 33 adaptedto receive one of the head blocks 34 and arranged in the top of the chamber 23 immediately in rear'of an inlet hopper 35 on said chamber. The head block 34 is maintained in elevated position in its guide 33 by a. longitudinal slide 36 on the forward end of which said head block .is adapted to rest. A springer springs 37 maintain the slide 36 in forwardly projected position but it is adapted to be automatically retracted by engagement of lateral lugs or projections 38 on the opposite sides of a wheel 39 with upstanding lugs or pro jections 40 upon the rear portion of said slide. The wheel 39 is arranged on a transverse shaft 41 suitably journaled on the rear portion of the bale chamber so that the periphery of said wheel 39 is adapted to project into the space within the bale chamber and to be engaged and actuated by a bale forced there-through. Owing to this construction itwill be seen that as a bale is formed and forced through the rear porpally disposed elevating mechanism which tion of the bale chamber, the wheel 39 will be caused to rotate once by reason of its contact with such bale so that when the lug or'lugs 38 upon the wheel engage the lug or lugs on the slide, said slide will be retracted against the tension of the springs 37 to permit the head block 34 to drop into the bale chamber.

The press or baler is provided with an automatically operating force feed mechanism consisting of a packing head or plunger 42- on the lower ends of two upright rods 43 depending from the intermediate portion of a horizontal bar 44 fixed intermediate the ends of two upright slide rods 45. The upper ends of the slide rods 45 are guided by the upper cross piece of an upright inverted U-shaped frame 46 rising from the intermediate portion of the main frame or body 1. The lower ends of the slide rods 45 have connected to them the lower ends of coil springs 47, the upper ends of which latter are attached to the upper portion of the frame 46. These springs 47 elevate the packing head 42 and the latter is adapted to be depressed by operatively connecting itto the press plunger 24. This operative connection consists of chains or the like 48 passed around guide pulleys 49 and having their upper ends connected to thelower extremities of the slide rods 45, and the opposite ends of said chains are connected to a cross rod 50 carried by the plunger. Owing to this construction it will be seen that as the plunger is retracted from beneath the hopper of the bale chamber the packing head 42 will be forced down through said hopper to feed the hay or other material into the chamber in advance of the plunger.

The hay, straw or the like, that is raked on to the platform 11 by the rake teeth 16 is directed on to a centrally and longitudidischarges itinto the hopper of the bale chamber. This elevator mechanism is of considerably less width than the rake platform, and for the purpose of directing the vator and immediately in rear of the relatively stationary rake 16. These rotary raking or feeding devices are similar and "hence a description of one will suffice for both. Each. consists of an upright shaft 51 suitably journaled in the platform and havinc; at its upper end a head 52 provided with radiating arms 53 carrying plates 54 (see Fig. 5). Pivotally connected to the latter are rake members 55 which are yieldably mounted. by means of springs 56.

hen the shaft 51 is rotated it will be noted that the rake members will brush the hay on to the lower portion. of the elevator. Thelower ends of the shafts 51 are connected by beveled gears 57 to transverse shafts 58 'journaled in suitable bearings beneath the rake platform 11 and having upon their outer ends sprocket wheels 59. The latter are connected by chains ()0 to sprocket wheels 61 fixed upon the outer portions of the wheels '2, the rotary raking or feeding devices being thus driven from said wheels.

, The elevating mechanism consists of a series of endless belts of usual form and construction, the preferred arrangement consisting of a short belt or apron. (32 arranged in a central opening in the rake platform 11 and adapted to discharge upon an upwardly and rearwardly inclined belt or apron 63 above which latter is a superposed belt or apron 64 to provide a force feed for the hay. The upper end of the elevator belt or apron 63 discharges upon the downwardly and rearwardly inclined belt or apron 65, which latter in turn dis charges into the hopper 35 of the press or bale chamber. These belts or aprons are arranged in a suitable supporting framework 66 and are driven by sprocket chain gearing 67,arranged on one side of said frame and including a sprocket wheel or gear on a transverse shaft 68 journaled in suitable bearings beneath the rake platform 11. The outer end of the shaft 68 has upon it a sprocketwheel 69 which meshes with one of the sprocket chains 60.

While the machine may be pulled, pushed or propelled by any suitable means, I preferably provide beneath the intermediate or rear portion of the main body 1 a transverse pivoted draft bar 70 to the ends of which are attached double trees 71 for draft animals.

72 denotes a suitable receptacle supported on the intermediate portion of the body for hoiding head blocks etc, and 73 denotes a long tudinal tray or receptacle similarly supported for holding bale fastening wires.
